As a relatively new 'MAC' user (got my first MAC last year, been on PC since DOS 3.2) I spent some time reading here and around the Internet about the pros and cons of 'AV for MAC'. At home, my router DLs about 25 'bad site' lists every day and blocks access, and only opens needed ports to the internet. Also running intrusion detection. VLANs separate the IOT stuff that won't ever get patches but has to be on the network, and guest access (who knows how safe they are), while also keeping home servers/file servers on their own limited-access VLAN. So I have tried to provide some level of protection even before the computer gets on the network. And of course, education of family.
I did try F-Secure for a short while (it was free from my ISP) and I do have it installed on the PCs along with Malwarebytes, but I removed it shortly after installing it on the MAC. At home I am not sure it's needed. If I ever get a real vacation and will be taking it about and connecting it to hotel WIFI and what have you, I will at least put that F-Secure back on there. Maybe make a 'mini router' and sit behind that in the hotel room (PFSENSE+PFBLOCKER)...
I am a bit leery of the 'just trust MAC', coming from decades in the PC world. But in the end, we all should be assessing our risks and choosing our poison appropriately.
